TROUBLE DIAGNOSIS EC-675 [VG33E] C D E F G H I J K L M A EC *: Any mode except OFF, ambient air temperature is above 25 °C (77°F). : Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.) CONSULT-II Function UBS00DFA FUNCTION *: The following emission-related diagnostic information is cleared when the ECM memory is erased. ● Diagnostic trouble codes ● 1st trip diagnostic trouble codes ● Freeze frame data 121 BR Heated oxygen sensor [Engine is running] ● Engine speed is below 2,800 rpm Approximately 0.4V [Engine is running] ● Engine speed is above 2,800 rpm BATTERY VOLTAGE 122 R/B Heated oxygen sensor [Engine is running] ● Engine speed is below 3,600 rpm after the fol- – Warm-up condition – Keeping the engine speed between 3,500 and 0 - 1.0V [Ignition switch: ON] ● Engine stopped [Engine is running] ● Engine speed is above 3,600 rpm BATTERY VOLTAGE 123 R/Y Heated oxygen sensor [Engine is running] ● Engine speed is below 3,600 rpm after the fol- – Warm-up condition – Keeping the engine speed between 3,500 and 0 - 1.0V [Ignition switch: ON] ● Engine stopped [Engine is running] ● Engine speed is above 3,600 rpm BATTERY VOLTAGE 124 B/R ECM ground [Engine is running] ● Idle speed Engine ground TER- MINAL NO. WIRE COLOR ITEM CONDITION DATA (DC Voltage) Diagnostic test mode Function Work support This mode enables a technician to adjust some devices faster and more accurately by following the Self-diagnostic results Self-diagnostic results such as 1st trip DTC, DTCs and 1st trip freeze frame data or freeze frame data Data monitor Input/Output data in the ECM can be read. Data monitor (SPEC) Input/Output specification of the basic fuel schedule, AFM, A/F feedback control value and the other Active test Diagnostic Test Mode in which CONSULT-II drives some actuators apart from the ECMs and also DTC & SRT confirmation The status of system monitoring tests and the self-diagnosis status/result can be confirmed. Function test This mode is used to inform customers when their vehicle condition requires periodic maintenance. ECM part number ECM part number can be read. |
